How to Use the ServiceNow Widget-Simple-List Misconfiguration Scanner

Recently, a valuable tool was shared on GitHub to assist ServiceNow users in assessing the security of their instances. This tool was created in response to the vulnerabilities discovered by Aaron Costello, a dedicated researcher who provided technical insights on data exposure risks due to misconfigured settings. You can find this tool on GitHub at https://github.com/bsysop/servicenow.

In this article, we’ll guide you through the steps to run this ServiceNow Widget-Simple-List Misconfiguration Scanner. By following these steps, you can proactively protect your ServiceNow instances from potential vulnerabilities.

Prerequisites: Before you begin, make sure you have the following prerequisites in place:

  1. Python 3.x: If you don’t have Python installed, you can download it from the official website at https://www.python.org/downloads/ and make sure to check the “Add Python to PATH” option during installation.

  2. Python ‘requests’ library: Install the ‘requests’ library using pip. Open your terminal or command prompt and run:

				
					pip install requests
				
			

Step 1: Clone the Repository

  1. Start by cloning the ServiceNow Widget-Simple-List Misconfiguration Scanner repository to your local machine. You can use the Git command if you have Git installed. Alternatively, you can download the repository as a ZIP file and extract it to your local machine.

				
					git clone <repository_url>
				
			

Step 2: Open a Terminal or Command Prompt

  1. Open a terminal or command prompt on your computer. You can do this by searching for “cmd” on Windows, “Terminal” on macOS, or using your favorite terminal emulator on Linux.

Step 3: Navigate to the Repository Directory

  1. Use the cd command to navigate to the directory where you cloned the repository. Replace <repository-directory> with the actual path to the repository directory on your computer.

				
					cd path/to/repository-directory
				
			

Step 4: Run the Scanner

  1. To scan a single URL, use the following command. Replace <your-service-now-url> with the URL of your ServiceNow instance.

				
					python servicescan.py --url https://your-service-now-url
				
			

If you have a list of URLs in a file (e.g., urls.txt), you can use the following command to scan multiple URLs:

				
					python servicescan.py --file urls.txt
				
			

Step 5: Review the Output

  1. After running the scanner, it will perform the scan and display the results in the terminal window. Review the output to check for any vulnerabilities or misconfigurations in your ServiceNow instance.

 

Conclusion: Using the ServiceNow Widget-Simple-List Misconfiguration Scanner is a proactive approach to ensuring the security of your ServiceNow instance. Regularly scanning for misconfigurations can help prevent data exposure risks. Remember to use this tool responsibly and only on systems for which you have explicit permission to test. Unauthorized scanning or testing can have legal and ethical consequences.

By following these steps, you can enhance the security of your ServiceNow implementation and protect sensitive information from potential threats.
